What is effective rent per square foot?

What is effective rent per square foot?

Turn the whole deal into one yearly dollar per foot so two buildings can share a scale.

This page belongs to a validation / pilot concept. It is not generally available.

Questions this page also answers

Usable or rentable?

Pick one and keep it. Mixing them creates a fake win.

Does load factor matter?

Yes. You may pay for hall you cannot sit in.

Is this the same as occupancy cost per foot?

Only if extras sit in the effective rent you used.

Why yearly?

Rooms already talk in dollars per foot per year.

Plain-language definition

Per square foot is the unit most rooms already speak.

Effective rent per foot is the deal, not the sticker, in that unit.

You must say usable or rentable. Those feet are not the same.

A load factor can move the number without moving the rent.

This page sits under Effective rent.

If extras matter, show occupancy per foot too.

The usual mistakes start with mixed feet.

Normalize the foot basis before the beauty contest.

Brokers should say the basis out loud. See tenant-rep analysis.

Investopedia defines net present value as later cash brought back to today. That idea is the spine of this page. See Investopedia on NPV.

Why it matters

Clients compare buildings in dollars per foot.

A cheap sticker on inefficient feet can lose.

Finance wants one unit across locations.

How it works

Write the cash list first. Then decide what the page is measuring.

  • Build the yearly effective rent.
  • Divide by the feet you chose.
  • Use the same foot basis on every option.
  • Name usable versus rentable on the slide.
Later cash boxes sit farther right and look smaller than year-one cash.
Later cash is smaller in today's dollars. This is a teaching picture, not a live model.

Formula in words. Effective rent per foot = yearly effective rent / chosen square feet.

See how to calculate it

Assumptions

  • The sample uses rentable feet. A usable-foot version would look higher.

Edge cases

Two buildings with different load factors need the same basis.

Common mistakes

  • Mixing usable and rentable.
  • Dividing a five-year total by one year of feet.

Decision implications

If the client thinks in seats, also show cost per person beside the foot number.

Compare this to related metrics

Occupancy cost per foot includes extras. Effective rent per foot may or may not.

See occupancy cost per square foot.

Limits

  • A foot number cannot score the floor plate.

When this should not drive the choice

  • Do not use it alone when one space wastes 20 percent of the floor.
